/*
The table reports regression estimates of the effect of Globo's edited coverage on the second round's vote shares in the 1989 presidential elections. Columns (1) and (2) reports baseline estimates on Lula's vote share. All specifications control for municipality and time fixed effects and first round's vote shares. Column (3) splits treatment status according to coverage of other TV broadcasters. Columns (3) and (4) repeat columns' (1) and (2) specification and estimate the effect of the edited coverage on Collor's vote share. Heteroskedasticity-adjusted standard errors clustered at the municipality level are reported
in brackets. Significantly different from zero at $99\% (***)$, $95\% (**)$ and $90\% (*)$ confidence level.
